Is there a way to mark a Standard as Inactive?

To inactivate a Standard, select the Standard and click on the Change button. Use the Status field dropdown menu to select Inactive. Click on the Update button to save the changes. After inactivating the Standard, the Last School Year field will be available to be updated. 

Inactivating Standards best practice is to do it in the new school year after rollover but before report cards are adjusted or teachers begin working on their gradebooks. Inactive standards will not be available when updating the report card layouts or for teachers when adding standards to assignments.
